Comparative Investigation of Lithium-ion Charging Methods Implemented via a Single DC/DC Converter

Picking an appropriate charging method for a certain implementation depends on several factors, such as charging time, complexity, capacity utilization, and charging effect on the state of health (SOH). A practical-based comparison for the common charging approaches under the same operating conditions is necessary to show the key features of each approach. This paper addresses the mentioned issue and presents a performance comparison between the common waveform-based charging strategies for Lithium-ion batteries. The performance comparison comprises all features mentioned above. A single DC/DC converter is created to implement the different charging strategies and validate the performance of each strategy for the same operating conditions.
